I understand the idea behind the OP. It takes elite talent, superstar talent, to really win in this league. The Jazz don't have that #1 guy. Even good teams like Memphis, the Rockets and the Clippers rarely get past the 2nd round of the POs. That said, it really only takes one guy to build around. The Warriors without Steph Curry might not be a playoff team. The Thunder without Durant are barely a .500 team as they showed last year.
If the Jazz could add one legit star player to the mix they currently have, that could put them into the contender tier. But it would have to be one extremely well considered, surgically precise player move to make that happen. Truthfully, I don't think the Jazz can make that move until they get a better read on how a few of their young players are going to turn out.
Right now, the only conclusions we can draw are that neither Trey Burke nor Derrick Favors are superstars in this league. Favors is a decent defensive-minded starting PF in the mold of a Brian Grant, and Trey is a rotation guard. Maybe you conclude that Alec Burks is an above-average scoring guard like a Monta Ellis of sorts. If so, then maybe Burke, Burks and Favors are guys you'd be willing to move for a star-level player.
If Trey Lyles really pans out in the next two years, that could make trading Derrick Favors more tolerable.
